Abstract
The invention relates to data processing methods and systems including: a method of database replication in which information strings are assigned to serialisation groups for processing. A method of memory management in which data is read from a storage space area whilst no data is written to it. A method of replicating a database in which a dynamic table is created to provided processing information for database members. A method of replicatin g a database wherein tasks are allocated to program components without program components interacting.
Claims (26)
1. A method of replicating information from a source system at a target system comprising the steps of:
i) receiving information strings from the source system;
and ii) assigning the information strings to serialisation groups for processing such that interrelated information strings are processed in the same serialisation group.
i) receiving information strings from the source system;
and ii) assigning the information strings to serialisation groups for processing such that interrelated information strings are processed in the same serialisation group.
2. A method as claimed in claim 1 wherein the information strings are journal entries from a source database.
3. A method as claimed in claim 2 wherein the journal entries are allocated to serialisation groups such that journal entries of the same type or related to other journal entries are processed in the same serialisation group.
4. A method as claimed in claim 2 or claim 3 wherein, when each database object is first encountered in a processing operation a temporary index object is generated containing the serialisation group and related processing information for that database object.
5. A method as claimed in claim 4 wherein, if a temporary index object already exists the serialisation group for a database object is assigned based upon the temporary index object data.
6. A method as claimed in claim 4 wherein if a temporary index object does not exist a full object name look-up of an assignment database is conducted, the serialisation group is obtained from the assignment database and a temporary index object is generated.
7. A method as claimed in any one of the proceeding claims wherein processing information for a database object is maintained in dynamic memory.
8. A method of managing memory space in a data transfer operation comprising the steps of:
i) defining a plurality of storage space areas;
ii) writing data to a first storage space area; and iii) reading data from the first storage space area whilst no data is written to the first storage space area.
i) defining a plurality of storage space areas;
ii) writing data to a first storage space area; and iii) reading data from the first storage space area whilst no data is written to the first storage space area.
9. A method as claimed in claim 8 wherein the data is database journal entries.
10. A method as claimed in claim 9 wherein the journal entries are consecutively written to the first storage space area until the first storage space area is at least substantially filled and then data is written to the next storage space area.
11. A method as claimed in claim 9 or claim 10 wherein each journal entry has an associated header that records the displacement to the next journal entry having the same serialisation group.
12. A method as claimed in any one of claims 8 to 11 wherein data is written to a second storage space whilst data is read from the first storage space.
13. A method as claimed in any one of claims 8 to 12 wherein each storage space has a storage space header which records the number of serialisation groups having journal entries within that storage space.
14. A method as claimed in claim 13 wherein when all data is read out of a storage space, the storage space header is decremented and the storage space is made available for data to be written to.
15. A method of replicating a database from a source computer system at a target computer system comprising:
i) receiving journal entries from the source computer system;
ii) checking the journal entries to see if any entry exists in a dynamic index giving processing information relating to a database member to which the journal entry relates; and iii) if an entry exists in the dynamic table, processing the journal entry according to the associated processing information; or iv) if an entry does not exist in the dynamic index, looking up the related processing information for the member in an assignment database; creating an entry and storing it in the dynamic index; and processing the journal entry according to the processing information.
i) receiving journal entries from the source computer system;
ii) checking the journal entries to see if any entry exists in a dynamic index giving processing information relating to a database member to which the journal entry relates; and iii) if an entry exists in the dynamic table, processing the journal entry according to the associated processing information; or iv) if an entry does not exist in the dynamic index, looking up the related processing information for the member in an assignment database; creating an entry and storing it in the dynamic index; and processing the journal entry according to the processing information.
16. A method as claimed in claim 15 wherein the dynamic index includes information as to whether a database member needs to be processed with one or more other database member.
17. A method as claimed in claim 15 or claim 16 wherein journal entries are temporarily stored before the replication process is performed.
18. A method as claimed in any one of claims 15 to 17 wherein the memory management method of any one of claims 8 to 14 is employed.
19. A method as claimed in any one of claims 15 to 18 wherein the replication method of any one of claims 1 to 7 is employed.
20. A method of replicating a database from a source computer system to a target computer system comprising:
i) receiving journal entries from the source computer system; and ii) allocating program components to process journal entries and update the target database, wherein a control program allocates tasks to program components and controls the program components substantially without program components interacting with one another.
i) receiving journal entries from the source computer system; and ii) allocating program components to process journal entries and update the target database, wherein a control program allocates tasks to program components and controls the program components substantially without program components interacting with one another.
21. A method as claimed in claim 20 wherein the target computer system implements parallel processing.
22. A method as claimed in claim 20 or claim 21 wherein the target computer system is a multi-processsor computer.
23. A computer system programmed to operate according to the method of any one of the preceding claims.
24. A computer program adapted to carry out the method of any one of claims 1 to 22.
25. A computer readable medium containing a computer program as claimed in claim 24.
26. A database replicated by the method of any one of claims 1 to 22.
